Grid division
Metal grate is such as ferrum, nickel, chromium, titanium, tantalum, molybdenum, stannum, indium, zinc, tungsten, platinum, manganese, magnesium, lead, it is preferable that the alloy by silver, copper, gold or aluminum or according to the metal of electric conductivity selection is made。It is usually taken such grid configuration: the level of the optical clarity of limited proportion between the width of the opening size of grid and the metal trace of grid reflector。
The size marking herein referring to fixed grid lattice is characterized as being: its pitch (pitch) (or its periodically), the width of conductive trace and thickness (or the opening formed in pitch)。
With reference now to Figure 15, the grid division of metal forming is described。
When first approximation, the optical transmittance T of metal forming is defined as the ratio of open surfaces and total surface。This ratio can be estimated according to the cycle a (that is, pitch) of single grid, which creates: T (%)=(ta)2/a2=t2, wherein t is the constant (we have square surface a × a, hole in this square have surface t.a × t.a) relevant to grid division。This formula allows to select suitable ratio t for given absorbance T。
When ratio t is known, it is possible to obtain the value of grid cycle a (with rice (m) for unit) based on electricity and light demand。
Viewpoint from electricity, give the operating frequency f being unit with Gigahertz (GHz), grid cycle should be lower than the operation wavelength of optically transparent plate aerial assembly many: a (m) < 0.3/ [t × K × (ε r) ^ (0.5) × f], wherein K is greater than the safety coefficient of 10, ε r is the dielectric constant (that is, ε r (air)=1) relative to air of the medium around metal forming。But, if metal forming is coated on substrate, it is also necessary to consider that ε r is equally high with substrate dielectric constant, although actual value is relatively low。
It is needs from the discreteness (discretion) of the viewpoint of light, optical clarity and light。The latter defines according to human eye acuity, and it is the ability that eyes distinguish the object of distance of separation d from observed range D。As shown on Figure 15, if the angle, θ m between two objects O1, O2 is more than 4.8 × 10-4Radian, then human eye can differentiate between two objects O1, O2。In the ideal case, from than have being referred to as of meansigma methods " near point (punctumproximum) " of 24 centimetres closer to observed range grid be not necessarily visible, which create: min=D × tan (θ m)=25.10 of d-2× tan (θ m)=120 μm。The very high raster resolution corresponding close to the metal trace width of 30 microns that this ideal situation creates with optical clarity is 80%。This situation for be not more than 400mm × 400mm grid surface be possible。
For the minimum observed range of 1 meter, min=1 × tan (θ m)=480 μm of d。
It is noted that the satisfied of light demand makes meeting of electricity demand。
Metal grate can physically (PVD) carry out, such as by grinding, vacuum evaporation, laser ablation etc., or carry out again by additive method, such as chemical deposition (silver-plated, copper facing, gold-plated, aluminize, tin plating, nickel plating ...), pass through silk screen printing, by electrolytic deposition, by chemical vapor deposition (CVD, PECVD, OMCVD ...) etc.。
In metal forming, the opening of metal grate can pass through standard photolithography; formed with relevant chemical etching according to the photomask transferred to by laser printer in storage (reserve) or mask; or formed by the lamination (tampography) after chemical etching, or formed by ion(ic) etching again with mask。
Grid can also pass through silk screen printing, prints (and relevant annealing) by conductive ink-jet, by electroforming, is done directly by decomposing organometallic write direct etc. via laser beam。Grid can also be made up of the transparent conductor material of such as indium tin oxide (IndiumThinOxide, ITO)。
